Description

The invention relates to an incontinence article in panty shape for receiving body exudates having a front abdominal portion and a rear back portion which are formed by separate and longitudinally spaced along a longitudinal central axis components, but to form a transverse in the transverse or hip circumferential direction abdominal and Back bands with a closed in the hip circumferential waist opening on both sides side seams manufacturer side, and with an absorption body having a crotch portion extending in the longitudinal direction between abdominal and back portion and insoluble with its body side facing the abdominal portion and the back portion in a respective overlap region is attached, wherein the belly portion, the back portion and the crotch portion together limit leg openings of the incontinence article, wherein in the abdominal portion and the back portion, there are provided first elasticizing means extending at a distance from each other and parallel to each other in the transverse or waist circumferential direction, thereby elastically elastinating the abdominal portion and the back portion, wherein in a crotch-side and leg-facing portion of the abdominal portion and the back portion second elastification means are provided, which extend from the two side seam areas in the direction of a longitudinal center axis of the incontinence article and extend along their extension in the direction of the longitudinal central axis of the incontinence article arcuately fanning with increasing distance from each other and thereby into the overlap region of the crotch section and belly section (also referred to as the front overlap area in the following) or of the crotch section and the back section (also referred to as the rear overlap area in the following) stretch, where they can be dazed there their elasticizing effect, in particular can be cut.

It is therefore a three-component incontinence article, wherein the abdominal portion, the back portion and the crotch portion form these three components. The belly portion and the back portion and the crotch portion are supplied as separate components of a manufacturing device or conveyed therein. In this case, the components are typically guided in a respective conveying plane in a flat or even expanded state. The belly section and the back section are supported in the later transverse direction of the incontinence article; they are guided spaced apart in the later longitudinal direction of the incontinence article. Thus, the later transverse or waist circumferential direction of the incontinence article is in the machine direction of the manufacturing apparatus. The aforesaid distance between the abdominal portion and the back portion is then effectively bridged by applying the crotch portion as the third component, forming an overlap region between the crotch portion and the abdominal portion and between the crotch portion and the back portion, wherein the three components in the respective overlap region are non-detachably joined together. Finally, the abdominal portion and the back portion are connected to each other at bilateral side seam portions as mentioned above. Such an incontinence article is known, for example DE 10 2007 055 628 A1 ,

Incontinence articles in panty form differ in principle from openable and closable incontinence articles in usual diaper form in that the hip circumference is already predetermined by the panty shape and the adaptation to different body sizes is achieved starting from a number of basic sizes by an elastic extensibility of the article. For this elastisierungsmittel usually, in particular in the form of tapes or threads, often referred to as Lycra threads, connected in the pre-stretched state (stretch bonding method) with chassis materials of the incontinence article, that is, they are in vorgedehntem state on the chassis materials z , B. fixed by means of adhesive. As a result of their bias, these elastification agents gather the chassis materials together and thereby form pleats, which typically run transversely to the direction of bias of the elastification means, in this case in the longitudinal direction of the article. The incontinence article or the elasticized chassis materials of the incontinence article can then be elastically stretched again when the incontinence article is put on the user like a panty.

For permanent connection of the abdominal portion or the back portion with the crotch portion in the respective overlap region, a full-surface joint, in particular bonding, or a non-full-surface joint can be selected. Often a full-surface application of adhesive or a substantially the entire area detecting spiral, applied by nozzles adhesive application is often used for joining large areas in prior art hygiene articles. But there are also hygiene products in which another way is taken; for example, teaches US 2004/0116886 A1 not to add large areas of the respective overlapping area; In this way, the shape and flexibility of the components in the overlap area should remain free and in any case not adversely affected by a joint connection.

US 7,250,549 teaches to provide each area of different adhesive properties in the respective front and rear overlap area. In this case, a region facing away from the hip, that is to say the center of the crotch section, has a greater areal weight of the adhesive than a region lying on the hip side in the transverse direction. The areas can be coated over the entire surface or line, spiral or punctiform with adhesive.

US 7,591,810 B2 teaches to connect the crotch portion and the abdominal portion or the crotch portion and the back portion only partially.

The object of the present invention is to improve the connection of the three components of the hygiene article, ie the connection of crotch portion and abdominal portion in the front overlap area and crotch portion and back portion in the rear overlap area, to an optimization with respect to the specific one discussed herein Type of three-component incontinence article in panty form and in view of the stress situations occurring there during operation is achieved.

This object is achieved in an incontinence article of the generic type according to the invention that the crotch portion by means of a plurality of in the overlap region of crotch and abdominal portion and provided in the overlap region of the crotch portion and back portion, transversely extending, parallel to each other and spaced from each other by glue-free strips of adhesive insoluble is connected to the abdominal portion and to the back portion, the adhesive strips covering substantially the entire respective overlapping area, and that the width of at least those adhesive strips lying inside with respect to optional marginal adhesive strips is at least 1 mm to at most 5 mm transverse to their extent, and that the width of the adhesive-free strips transversely to their extension is at least 1 mm to at most 15 mm.

It has been found according to the invention that with such an insoluble addition of the components, the amount of adhesive material required for this purpose can be reduced compared with a full-area or, for example, spiral adhesive application without any disadvantages. It has also been found that, when using a plurality of transversely extending adhesive strips, the forces typically occurring in the longitudinal direction during operation of the hygiene article, which are introduced in the overlapping region or over the overlapping region from the crotch section into the abdominal section or into the back section, are equally well absorbed can be when the plurality of adhesive strips extend substantially over the entire extent of the respective overlap region. However, this does not mean that the adhesive must imperatively extend to the respective geometric edge of the overlapping area; rather, it is preferred that the adhesive maintain a certain distance, on the order of one millimeter or less, from the geometric edge of the overlap area, to prevent adhesive from leaking out of the overlap area and contaminating the manufacturing device or even becoming visible on the finished product. It has also proved to be advantageous that the plurality of adhesive strips extends in the transverse direction, specifically in view of the fact that forces of a fully absorbed absorption body typically act in the longitudinal direction, ie transversely to the extent of the adhesive strips, due to gravity. These forces can be forwarded even better and more uniformly over the respective overlap region in the hip circumferential direction of the abdominal portion and the back portion or be absorbed by these due to the transverse extent of the adhesive strip. It also comes in this way to a lesser extent to a contraction or shirring of the overlap region in the transverse direction, so to a lesser extent disturbing pleats, which would then run in the longitudinal direction. It has been found in accordance with the invention that such an inventively designed adhesive application is suitable for counteracting excessive pleating, wrinkling or ruffling, which is favored or tended to be caused by the first and optionally also the second elastification agents.

It has further been found that the adhesive application according to the invention in the form of a plurality of transversely extending adhesive strips in combination with the mostly nonwoven-based or nonwoven materials or composites of the stomach portion and the back portion and optionally also the crotch portion are suitable, on the outer side of the overlap region form visible and / or haptic perceptible structure, which harmonizes or coincides with the visually and / or haptic recognizable course of the elastification in the respective overlap region. In this way, the course of the elasticizing agents in the overlapping region, where these elastification agents are often also deactivated, can be laminated, so that they and the adhesive-related structure can no longer be distinguished. This is visually appealing.

The application of the multiplicity of adhesive strips which essentially cover the entire respective overlapping region is typically carried out in the course of a so-called contact application, preferably using stencil technology. For this purpose, in principle known gluing devices, for example the system TrueCoat ^™ from Nordson Germany from Erkrath, Germany, can be used. The TrueCoat ^{TM system} is a slot die surface applicator, with slot die applicators configurable for precise, continuous or intermittent application of adhesive. Also, the application of the adhesive using a sheet with strip-shaped recesses is possible. The gluing is advantageously carried out in the machine direction of the material forming the belly portion and back portion, ie with stretched in the machine direction adhesive tape, so that the plurality of adhesive strips - as already mentioned several times - in the finished product then substantially transverse to the longitudinal direction, ie in the transverse or Hüftumfangsrichtung, runs.

Furthermore, it proves to be advantageous if the gluing of the webs in the machine direction is clocked, d. H. Glue is actually applied only in the already mentioned overlap areas between crotch section and abdominal section or between crotch section and back section.

It also proves to be advantageous if the width of adhesive strip transversely to its extension is at least 1 mm to at most 4 mm and more particularly to at most 3 mm and preferably 2 mm.

The width of the adhesive-free strips is expediently at least 1 mm to at most 10 mm, in particular to at most 5 mm and more particularly to at most 3 mm, transversely to their extent.

As already mentioned, it is conceivable that in the respective overlapping region, that is to say the rear and / or the front overlap region, a wider adhesive strip is provided at the edge. This means that in a longitudinally hip-side edge region of the overlap region and / or in a longitudinal region of the overlap region facing away from the hip in the longitudinal direction, a broader adhesive strip extending in the transverse direction can be provided. This hip-side edge region or hip-facing edge region of the overlapping region covers in each case at most 20%, in particular at most 18%, in particular at most 15%, in particular at most 12%, in particular at most 10%, of the longitudinal extent of the respective front or rear overlapping region. In the longitudinal direction between these edge regions then the plurality of narrow and transversely extending adhesive strips are provided in each case. The width of said peripheral adhesive strips transversely to their extension is at least 5 mm, in particular at least 8 mm, in particular at least 12 mm, in particular up to 20 mm, in particular up to 16 mm, in particular up to 14 mm. If a wider adhesive strip is provided in the overlap region only at one edge, then it proves to be advantageous if this wider adhesive strip is provided on the hip-distant edge region of the overlapping region in order to achieve a stable joint there, which prevents tearing.

It proves to be particularly advantageous if the ratio of the width of adhesive strip to the width of immediately adjacent adhesive-free strips 0.2-3.0, in particular 0.2-2.0, in particular 0.2 to 1.5, in particular 0, 2-1.0, in particular 0.4-0.8, in particular 0.5-0.7. Thus, a finely and evenly distributed sequence of adhesive strips and adhesive-free strips is provided in an advantageous manner, which provides a uniform joining region distribution and, associated therewith, a joint stability in the overlapping region with uniform distribution of possible stiffening by the adhesive strips. In addition, a visually appealing visually and / or haptic perceptible structure is achieved. It also reduces the isolated perceptibility of the elastification agent in this overlap area.

Also with regard to a uniform as possible visually and / or haptic recognizable design or structuring due to the large number of adhesive strips, it proves to be advantageous if the width of at least those adhesive strips that are inside with respect to optional edge-side adhesive strips, ie in the longitudinal direction between marginal adhesive strips, respectively is the same size.

Furthermore, it proves to be advantageous if the width of the adhesive-free strip is equal in each case.

Regardless of the specific configuration and arrangement of the plurality of adhesive strips, it proves to be advantageous if the total area of the adhesive strips relative to the area of the overlapping area of crotch section and abdominal section or of crotch section and back section is 35-60%, in particular 40-55% and more particularly 40 -50%.

Furthermore, it proves to be advantageous if the weight per unit area of the adhesive coating in the adhesive strips is 2-20 g / m ² , in particular 2-15 g / m ² , in particular 2-10 g / m ² , in particular 5-10 g / m ² , wherein the basis weight is preferably the same for all adhesive strips.

In order to achieve a uniform introduction of forces which are caused in the use of the hygiene article by absorbed in the absorbent body liquid in the formed by the abdominal portion and the back portion in the transverse or Hüftumfangsrichtung continuous abdominal and back band, it proves to be advantageous if the Area of the overlapping area of the crotch portion and the abdominal portion relative to the surface of the abdominal portion is at least 12%, in particular 15-40%, in particular 15-35%, in particular 15-30%, in particular 20-30%, in particular 22-30%. Furthermore, it proves to be advantageous if the surface of the overlapping region of crotch portion and back portion relative to the surface of the back portion at least 20% in particular 20-45%, in particular 20-40%, in particular 22-40% in particular 25-40%, in particular 28-40 % is.

According to a preferred embodiment of the incontinence article according to the invention, it proves to be advantageous if in the overlapping region of the crotch section and abdominal section and / or in the overlapping region of the crotch section and back section two outer marginal adhesive strips, ie a hip-distant and a hip-near edge adhesive strip, and in the longitudinal direction between these a plurality are provided by inner adhesive strips, wherein the width of the peripheral adhesive strips is greater than the width of the inner adhesive strips, in particular at least 4 times, in particular at least 5 times and more preferably at most 8 times, especially at most 7 times Width of the inner adhesive tape is. It would also be conceivable that a plurality of wider edge-side adhesive strips are provided on a respective hip-side or hip-facing edge region of the respective overlapping region, as long as the edge region does not exceed the previously explained dimensions in the longitudinal direction.

In a preferred embodiment of the incontinence article according to the invention, at least 8, in particular at least 10, adhesive strips are provided in the overlapping area of the abdominal section and crotch portion, and at least 15, in particular at least 18 and more particularly at least 20 adhesive strips are provided in the overlapping area of back section and crotch section.

The above-mentioned second elastification means, which are provided in a step-side and the leg openings facing portion of the abdominal portion and the back portion extend along its extension in the direction of the longitudinal central axis and in the direction of the respective overlap region arcuately fanning with increasing distance from each other. In this way, the restoring force acting in the area of the step-side and the leg openings facing the region of the stomach and the back portion can be influenced. It can be reduced in the direction of the longitudinal center axis in this way.

Furthermore, it proves to be advantageous if the first and / or the second elastification means extend in the overlapping area of the crotch portion and the abdominal portion and in the overlapping area of the crotch portion and the back portion parallel to the adhesive strips. Typically, the elastification means are introduced in such a way that they extend endlessly in the transverse or hip circumferential direction, that is to say in the machine direction of the flat material webs forming the later belly section and back section. They therefore extend at least initially throughout the entire transverse extent of the incontinence article. In this way, it is typical for the absorption body to be understressed by the elastification means in the respective front or rear overlapping area of crotch section and abdominal section or crotch section and back section, so that the absorption body of the crotch section comes to rest above the elastification means or body-facing. In such case, it proves to be particularly useful if the elasticizing agents, at least where they undertake the absorption body, are behaved in terms of their elasticizing effect; For this they can typically in this area along their transverse extent, in particular multiply cut or in any other way, for. B. by the action of ultrasound or use of knives, be de-elasticized. Nevertheless, it is found that the course of both the initially introduced elastification agent and the elasticizing agent deactivated or de-elasticized in the respective overlapping area can be recognized from the outside of the incontinence article. As already mentioned, however, this can be laminated by providing the plurality of narrow adhesive strips, which is to be regarded as a particular advantage of the present invention.

The above-mentioned arc-shaped fanning can preferably be designed such that a distance between the second elastification means in a respective side seam region is 3 to 8 mm and further inward in the direction of the longitudinal central axis in the region of an absorption body edge between about 7 and 35 mm, in particular between 12 and 30 mm. Advantageously, the second run Elastifizierungsmittel in the overlapping region at least in the region of the longitudinal central axis in the transverse direction and preferably also parallel to each other.

This fanning out of the second elastification agents can also be described quantitatively in greater detail. For example, in 1 shown second elasticizing agent of the back portion in the side seams a minimum distance of 3 to 8 mm from each other (distance from immediately adjacent elastification) and at an absorbent body edge or a longitudinal edge of the crotch section a maximum distance (distance from immediately adjacent elastification) of 7 to 35 mm from each other. A fanning degree F can be defined as follows: F = (AB) / B x 100%.

This degree of fanning can advantageously be between 50 and 900%, in particular between 100 and 700% and more particularly between 150 and 550%. It is advantageously larger in the back section than in the belly section. In this case, the sizes A and B are defined as the distance between the longitudinally outermost second elastification means and the longitudinally innermost second elastification means (ie, not the spacing of immediately adjacent elastification means), namely A as the maximum spacing, in particular at the longitudinal edge of the crotch portion. and B as the minimum distance, especially in the side seam area.

As the first and / or second elastification thread- or tape-like elasticizing means, such as rubber or polyether or polyester polyurethane threads, preferably elastic, such as Lycra ^® are preferably - or Spandex ^® filaments used. The first elastification agents preferably have a thread thickness of 400-1500 dtex, in particular of 500-1400 dtex, in particular of 800-1400 dtex, in particular of 1000-1400 dtex, more particularly of 1100-1400 dtex. The second elastification agents preferably have a thread thickness of 500-1000 dtex, in particular of 600-1000 dtex, more particularly of 700-900 dtex.

The thread strength of the elastification agent is given in the unit dtex (1 dtex = 1 g / 10000 m). The thread thickness is according to the Test Guidelines BISFA, The International Bureau for the Standardization of Man-made Fibers, Test Methods for Bare Elastane Yarns, Edition 1998, Chapter 5: "Determination of Linear Density" certainly. The thread thickness or linear density is determined by determining the mass of a specimen of a known thread length of 1000 mm (separated under a standard bias of 0.1 ± 0.01 mN / tex) after conditioning under standard conditions (23 ° C ± 2 ° C, 50 ° C) % ± 5% relative humidity) in the relaxed state.

The thread thickness (in dtex) is calculated from the quotient of the mass (in g) by the length of the section (in m) multiplied by the factor 10000.

For this purpose, five sections, each about 1300 mm in length of the filamentary or band-shaped elastic means are cut off under the lowest possible tension of a roll or package, and at irregular intervals of at least 2 m. These five sections are relaxed tensionless and allowed to rest under standard conditions for at least four hours. Then, a specimen of 1000 mm ± 1 mm in length is cut off from the respective 1300 mm long section while maintaining the section under a bias of 0.1 mN / tex. These separated specimens of 1000 mm length are weighed to an accuracy of ± 1% of their expected mass. For each test specimen, its thread thickness is obtained by multiplying the respective mass by the factor 10000 in dtex. From the five samples, the arithmetic mean is calculated, which is used as thread size for the purposes in question.

The first and / or second elastification means are preferably fixed under a bias of 2.5-6.0 to the chassis-forming shell materials of the waist portion and the back portion (stretch-bonding method). The prestressing is defined as the degree of stretching of a stretched elastification agent relative to the unstretched / relaxed initial state of the elastification agent in the state of application and fixation of the elastification agents in the production machine. The degree of expansion is thus calculated as the ratio of the stretched length L '(= initial length L + ΔL) to the initial length L, ie L' / L. The first elastification means are preferably fixed under a pretension of 4.0-6.0, in particular of 4.5-5.5, the pretension of which is preferably greater than that of the second elastification means. The second elastification means are preferably fixed under a pretension of preferably 2.5-5.0, in particular 3.0-4.5.

The first and / or second elastification means may be fixed in different ways to the chassis-forming wrapping materials of the stomach section and back section. Elasticizing means extending parallel to the transverse or hip circumferential direction, such as the first elasticizing means, are preferably fixed by means of single-strand glueing. Single strand glueing means that the top of each elasticizer is first coated with glue and then sent to lamination between two chassis materials. A further possibility for fixing elasticizing agents consists of embedding the elasticizing agents in a glue bed between two layers of chassis material, wherein at least one layer has adhesive-coated areas over its entire area. In particular, the fixing takes place in a glue bed in elastification means which have a change of direction along their course, as for example the second elastification means are formed which fan out along its extension in the direction of the longitudinal central axis of the incontinence article and extend with increasing distance from each other.

It proves to be advantageous if the second elastification means are fixed in a glue bed between Chassismateriallagen. In such a case, a laminate results in which the layers are continuously connected throughout. With sufficient elongation of this laminate, a single planar flat material web is produced, which can then be joined with further constituents without forming indeterminate crimps, as can occur in single-strand gluing, in which adjoining chassis material layers are connected only along the glued strands. The glue bed fixation of the second elastification means therefore proves to be advantageous especially in the joining of the crotch section with the belly section or back section.

Furthermore, it proves to be advantageous if the first elastification means in the abdominal portion and / or in the back portion are fixed by single strand glue between Chassismateriallagen. In the area of the first elastification agents, greater flexibility of the chassis material layers is certainly desirable since there is no further formation of laminates.

In a further development of this inventive concept, it proves to be advantageous if the first elastification means are fixed in the abdominal portion and / or in the back portion by single-strand gluing between a body facing away Chassismateriallage and a body facing Chassismateriallage and the body facing Chassismateriallage dominated the overlapping longitudinal end of the crotch portion on the body-facing side or overlaps. Since the body-facing chassis material layer is typically formed from soft non-woven fabrics, a soft, skin-friendly transition to the crotch portion can thus be achieved in the longitudinal direction.

The crotch section advantageously comprises a liquid-impermeable backsheet material and a nonwoven topsheet material, between which the absorption body is arranged. In this case, the backsheet material and the nonwoven topsheet material to a certain extent form the chassis of the crotch section. In development of the invention of particular importance, it proves to be advantageous if the backsheet material and / or the topsheet material in the transverse direction form an overhang on the absorption body and this overhang - in the sum on both sides of the absorption body, ie in the sum left and on the right - at least 25%, in particular 30-50% further, in particular 35-50% further, in particular 38-48%, in particular 40-45%, based on the greatest width of the crotch section (ie, based on the maximum extent of the crotch section in the transverse direction) ,

This relatively large overhang of backsheet material and / or topsheet material on both sides of the absorbent body thus means a wide crotch section with a relatively narrow absorption body. This makes it possible to provide Beinelastifizierungsmittel extended along the leg openings in the crotch portion, which have a relatively large distance from the material-rich and thus rigid absorption body. This in turn results in a good sealability and adaptability of the two-sided leg opening edges of the crotch section. In that case, the material-rich absorption body, which is torsionally rigid with respect to thin chassis materials, impedes the formation of a liquid-tight leg termination only slightly; It must therefore not be used to form a fluid-tight leg end with extremely high voltages, which in turn has a positive effect on the comfort of the incontinence article.

In a further development of the invention, it proves to be particularly advantageous if the leg elastics end in the longitudinal direction at least 10 mm, in particular at least 20 mm in front of the second elastification. It is particularly advantageous if the leg elastics end in the longitudinal direction in front of the belly section and / or in front of the back section. Therefore, the tension and restoring force exerted by them does not influence the stress ratios provided according to the invention within the area of the abdominal portion and the back portion facing the crotch side and the leg openings, in which the fanning out second elastification means are provided.

As Beinelastifizierungsmittel preferably thread or band-shaped elastomers, such as rubber or Polyetherpolyurethan- or Polyesterpolyurethanfäden, preferably elastic threads such as Lycra ^® - or Spandex ^® threads used. The leg elastomers are preferably a thickness of 300-1500 dtex, in particular of 500-1200 dtex, more particularly of 500-900 dtex.

The leg elastomers are preferably fixed to the chassis-forming shell materials of the crotch portion under a bias of 1.5-6.0, more preferably 2.5-4.5.

The chassis forming materials of the waist section and / or back section preferably comprise nonwoven materials such as spunbonded nonwoven, carded nonwoven or through air bonded carded nonwoven webs. Particularly preferably, the chassis-forming material of the belly section and / or back section comprises a spunbonded material. The nonwoven materials used for the abdominal portion and / or back portion advantageously have a basis weight of 10-30 g / m ² , more preferably 15-25 g / m ² . Particularly preferably, the belly section and the back section comprise a spunbonded nonwoven, in particular made of polypropylene, in particular with a basis weight of 15-25 g / m ² . Low basis weights of the chassis-forming materials of the abdominal portion and / or back portion, in particular in the form of comprising or consisting of nonwoven materials allow due to their flexibility particularly advantageous the formation of the visually and / or haptic perceptible structures according to the invention.

The crotch portion advantageously comprises a liquid impermeable backsheet material and a nonwoven topsheet material. The backsheet comprises in particular a film, in particular a basis weight of 8-20 g / m ² , in particular of 8-16 g / m ² , in particular of 8-14 g / m ² . In particular, the backsheet comprises a liquid-tight but nonetheless breathable, ie water vapor permeable, in particular microporous film.

The absorbent body includes body fluid absorbing materials such as natural or synthetic fibers, especially cellulosic fibers, preferably in the form of pulp fluff. The absorbent body preferably also comprises superabsorbent materials (SAP), in particular based on surface-crosslinked, partially neutralized polyacrylates.

The crotch portion or the longitudinal edges of the crotch portion, which delimit the leg openings, may be straight or arcuately contoured. The step-facing transverse edges of the abdominal portion and the back portion, which also delimit the leg openings, are advantageously and preferably arcuately contoured.

Further features, details and advantages of the invention will become apparent from the appended claims and from the drawings and the following description of a preferred embodiment of the incontinence article according to the invention. In the drawing shows:

The figures show a total with the reference numeral 2 designated incontinence article in panty form for recording solid and liquid body exudates. The incontinence article 2 is made of three largely independently manufacturable components, namely a front belly section 4 , a rear back section 6 and an absorbent body disposed therebetween and an absorbent body 7 comprising step section 8th formed, wherein the crotch section 8th in a longitudinal direction 9 of the incontinence article 2 is extended and with a substantial area of the abdominal portion 4 on the one hand and the back section 6 on the other hand overlaps and in the overlapping area in the manner to be described later in the manufacturer is inextricably linked. How out 1 As can be seen, this leads to an H-shaped basic structure of the incontinence article. In the 1 The components joined together are then used to form the panty form at respective lateral longitudinal edge portions 10 . 12 of the belly section 4 and the back section 6 likewise connected to one another by conventional joining methods by the manufacturer, as a result of which side seam areas are provided on both sides 14 be formed. In this made by the manufacturer panty-shaped state of the incontinence article 2 the belly section extend 4 and the back section 6 in a transverse or hip circumferential direction 16 continuously and thus define with her waistband 17 a hip opening closed in the hip circumferential direction 18 ; furthermore they limit together with the crotch section 8th leg openings 19 through which the user applies the incontinence article like a panty.

The belly section 4 settles in a hip area 20 and in a crotch-side and leg openings 19 facing area 22 divide. A corresponding subdivision is in the back section 6 provided, and also in a hip-side area 24 and a crotch-side and leg openings 19 facing area 26 ,

In the hip area 20 of the belly section 4 and in the hip area 24 of the back section 6 are first elastification agents 28 . 29 provided, which may be in particular thread-like elasticizing agents, such as Lycra threads, in the pre-stretched state, in the so-called stretch-bonding method, with the flat materials (chassis materials) of the abdominal portion 4 and the back section 6 are connected. These first elastification agents 28 . 29 extend in the transverse or waist circumferential direction 16 from a side seam area 14 on the other hand.

The crotch-side and leg openings 19 facing section 22 and 26 of the belly section 4 or the back section 6 have one of the transverse or waist circumferential direction 16 deviating in the direction of a transverse central axis 30 of the crotch section 8th tapered edge contour 32 respectively. 34 , This edge contour 32 . 34 is also in the presentation after 1 arched and therefore to limit the leg openings 19 suitable.

Through this course of the step-side and the leg openings facing area 22 respectively. 26 also becomes a relatively large overlap area 36 . 38 between crotch section 8th and belly section 4 or back section 6 realized, with regard to a tear-resistant connection of crotch section 8th and belly section 4 or back section 6 is essential.

The respective crotch-side and leg openings 19 facing area 22 . 26 of the belly section 4 or the back section 6 is also formed elasticized. There are second elastification agents 40 respectively. 42 intended. The second elastification agents 40 . 42 each extend from the side seam areas 14 in the direction of a longitudinal central axis 44 of the incontinence article. How out 1 it can be seen, fan the second elastification 40 . 42 in the direction of the longitudinal central axis 44 on. This means that the distance between them in the direction of the longitudinal center axis 44 increases. The second elastification agents 40 . 42 cross the crotch section 8th , You can in the area below the absorption body 7 deactivated, ie be dazed their elasticizing effect.

How out 2a The step section can be seen in FIG 8th a liquid-impermeable backsheet material 62 , which may in particular be formed from a breathable, but liquid-tight film material, and a, preferably based on nonwoven topsheet material 64 , Between the backsheet material and the topsheet material is the absorbent body 7 (shown only schematically) arranged. In the case exemplified, the backsheet material forms 62 in the transverse direction 16 an overhang 66 over the absorbent body 7 , The topsheet 64 projects beyond the absorption body 7 in the transverse direction 16 only relatively small, and on both sides of the absorption body 7 is in the longitudinal direction 9 in each case an upstanding barrier means 68 is provided, which is typically referred to as an upstanding cuff or cuff element and is preferably formed from a hydrophobic, in particular liquid-impermeable nonwoven material which extends in the transverse direction 16 preferably up to lateral longitudinal edges 69 of the crotch section 8th extends. The distal ends 70 the barrier agent 68 are with other elastification agents 72 provided which the barrier means 68 in the use of the incontinence article against the user's skin surface. The lateral barrier means 68 are over schematically indicated fixations 76 . 77 on the topsheet 64 or set to itself in a C-folded configuration. Outside the absorption body 7 So in the area of the overhang 66 are also leg elastomers 78 provided, preferably with a certain distance from the material-rich and thus rather rigid absorption body 7 run on the one hand to exert no additional strain or torsional forces on the absorbent body, which could adversely affect its absorption behavior, and on the other hand to realize a largely unaffected by the absorbent body liquid-tight leg ending. These leg elastomers 78 ends in the longitudinal direction 9 with a clear distance of in particular at least 10 mm, preferably at least 20 mm in front of the second elastification agents 40 and 42 of the belly section 4 or the back section 6 , Preferably, these leg elastomers end 78 longitudinal 9 in front of the belly section 4 and the back section 6 ,

The following is the fixation of the crotch section 8th in the front overlap area 36 with the belly section 4 and in the rear overlap area 38 with the back section 6 described. As based on the 3 and 4 it can be seen, this is not a full-surface adhesive application, but a variety of provided in the overlap region, in the transverse direction 16 extended and parallel to each other adhesive strip 80 provided by adhesive-free strips 82 spaced apart from each other. The adhesive strips 80 capture or overlap substantially the entire overlap area 36 . 38 , In the case illustrated by way of example, but not necessarily, in a longitudinally hip-side edge region 84 and in a longitudinally hüftabgewandten edge region 86 of the respective overlapping area 36 . 38 wider marginal adhesive strips 88 and 90 intended. The respective marginal, ie hip-facing and hüftfernen adhesive strips 88 . 90 are formed with a larger strip width than the plurality of between them and inner adhesive strips 80 , In an exemplary embodiment, the width of the marginal adhesive tape is 88 . 90 transverse to its extension 14 mm, the width of the inner adhesive strips 80 2 mm and the width of the adhesive-free strips 82 is 3 mm. In the exemplary and preferred illustrated case have the inside adhesive strips 80 preferably all the same width, and preferably also the distances between them, so the width of the adhesive-free strips 82 , equal. Nevertheless, the explanations given at the outset regarding the dimensions and ratios described there as well as the basis weight of the adhesive coating apply to the adhesive strips. Also the area of the front and rear overlap area 36 . 38 based on the area of the belly section 4 or the back section 6 lies within the preferred limits explained above.

It also recognizes 3 in synopsis with 1 in that the second elastification agent 40 . 42 in the respective overlap area 36 . 38 parallel to the adhesive strips 80 run. Also a few of the first elastomers 28 run in the illustrated case in the front and rear overlap area 36 . 38 (but on the body-facing side of the crotch section). Also the second elastification agents 40 . 42 were in the transverse direction 16 introduced continuously; they are in the respective overlap area 36 . 38 deelastified by measures mentioned above. It turned out, however, that the second elastification agents remain recognizable even in the de-elasticized state, as explained in the beginning. However, they are due to the variety of adhesive strips 80 laminated, and thus their recognizability is reduced in an inventive way.

In the preferred case, the second elastification means are in a glue bed 92 between chassis material layers 94 and 96 respectively. 95 and 97 fixed (see 5 ). The glue bed 92 is on one of the Chassismateriallagen 94 . 96 respectively. 95 . 97 applied, then then the second elastification agents 40 . 42 preferably endlessly inserted or inserted and overlaid and laminated by the further chassis material layer. In this way, the second elastification agents 40 . 42 fixed and the Chassismateriallagen 94 and 96 respectively. 95 and 97 continuous with each other. In the body-facing Chassismateriallage 94 . 95 it is a breathable fiber fleece, which is the extension of the belly section 4 or back section 6 equivalent. At the Chassismateriallage 96 . 97 it is a contrast set inside nonwoven material. It ends in the longitudinal direction 9 in the case shown preferred before the longitudinal end 98 . 99 of the crotch section 8th ,

In the case exemplified and preferred, the first elastification means 28 . 29 by single strand glueing between the body facing away Chassismateriallage 94 respectively. 95 and another body-facing Chassismateriallage 100 . 101 fixed. The further Chassismateriallage 100 . 101 is again formed by a nonwoven material. The body-facing and the body facing Chassismateriallage are exclusively by the stranded first elastic means 28 . 29 connected to each other, so only along the extension of this first Elastifizierungsmittel 28 . 29 , The skin-friendly nonwoven materials are therefore not fixed surface-to-each other, but they can stand out from each other and form pleats or ruffles, in particular due to the elasticizing effect. The body facing Chassismateriallage 100 . 101 extends in the case shown preferred both in belly section 4 as well as in the back section 6 over the respective longitudinal end 98 . 99 of the crotch section 8th on its body-facing side. It thus overlaps this material transition and thus prevents a discontinuity leading to skin irritation.

One recognizes in 5 further, that the backsheet 62 of the crotch section 8th on its side facing away from the body a coating 102 having. This coating 102 is a nonwoven coating of the substantially liquid impermeable backsheet 62 , The coating 102 extends in the longitudinal direction 9 but not over the entire length of the backsheet 62 but ends relatively short within the front and rear overlap area 36 . 38 , Outside the overlap area is the coating 102 over the entire extension of the body side facing away from the backsheet 62 intended. The coating 102 preferably consists of a nonwoven fabric, in particular of a spunbonded nonwoven, in particular of polypropylene, in particular with a basis weight of 10-20 g / m ² , in particular of 12-17 g / m ² .

Finally shows 6 a schematic view of an incontinence article according to the invention in the finished configured state, in which the abdominal portion 4 and the back section 6 through the formation of side seam areas 14 are joined together. Only schematically indicated are due to the contractive effect of the first and second elastification agents 28 . 29 . 40 . 42 formed pleats or ruffles 104 , which are formed as a result of fixing the elastification in pre-stretched state on the chassis materials (Stretchbondverfahren). Due to the large number of relatively fine adhesive strips 80 in the respective overlap area 36 . 38 from crotch section 8th and belly section 4 or back section 6 becomes a visually and / or haptically perceptible structure 106 at the outer side of the incontinence article in the respective overlap area 36 . 38 formed, which is shown here only hinted. It has been found according to the invention that the strip-shaped adhesive penetrates into the three-dimensionally porous and otherwise breathable nonwoven materials which are typically used as chassis materials and to such an optically and / or haptically perceptible structure 106 leads, which may prove advantageous as explained above. In addition, the connection leads from step section 8th and belly section 4 or back section 6 through the multitude of relatively narrow adhesive strips 80 to a very economical adhesive consumption, while still providing the necessary holding forces for secure joining of the three components together.

7 illustrates the dimensions, dimensions and ratios of an incontinence article according to the invention. One recognizes first that the position of the transverse central axis 30 the total length of the incontinence article when laid flat (corresponding to 1 ) halved. The transverse center axis 30 also forms a first in the transverse direction 16 extending folding axis about which the components are folded within the manufacturing machine to the longitudinal edge portions 10 . 12 from belly section 4 and back section 6 for fixing and forming bilateral side seam areas 14 to bring one over the other. This typically still takes place under the guidance of endless the respective belly section 4 and back section 6 forming flat materials, so even before the separation of the article instead. One recognizes the length L1 between the transverse central axis 30 and the respective waistband 17 , Furthermore, one recognizes the extension L2 of the respective side seam or the side seam region 14 longitudinal 9 , which is also the length of the respective longitudinal edge portion 10 and 12 equivalent. According to the invention, the ratio L2 / L1 is at least 0.42.

Furthermore, one recognizes the distance L4 of the outermost hip-facing first elastification agent 28 . 29 longitudinal 9 from the innermost stepping first elasticizing agent 28 . 29 , According to the invention, the ratio L4 / L1 is at most 0.3.

It can further be seen that the first elastification agents 28 . 29 have a distance d ₁ from each other which is at least 20% greater than that in the side seam area 14 certain distance of the second elastification agent 40 . 42 from each other. In the preferred case, the first elastification agents 28 . 29 all the same distance d ₁ from each other, which is at least 10 mm, in particular 10 to 15 mm. The ratio d1 / L4 is preferably 0.08 to 0.25.

Furthermore, one recognizes L3 as the extension of the belly section 4 and back section 6 longitudinal 9 , which for the belly section 4 especially 135-260 mm and for the back section 6 especially 200-320 mm.

Also shown is the extension Q of the belly section 4 or the back section 6 in the transverse direction 16 , which is in ratios L2 / Q or L4 / Q.

The first elastification agents 28 . 29 have at least 20% greater thread strength than the second elastifiers 40 . 42 , They are also with at least 10% greater bias with the Chassismateriallagen in the abdominal section 4 and in the back section 6 fixed as the second elastification agent 40 . 42 ,

Reference is made to the further preferred given dimensions, dimensions and ratios.

Out 8th and 9 is the structure of the absorption body 7 in plan view and in a sectional view along the longitudinal center axis 44 seen. The absorption body 7 includes starting from its side facing away from the body a base layer 120 of cellulosic fiber material with an exemplary basis weight of 176 g / m ² . Depending on the exact planar extent, the base layer contains 10 to 14 g of cellulosic fiber material.

On the base layer 120 is an absorbent layer 122 filed, which is at least in terms of the basis weight of absorbent material three-dimensional topology. It points in a central area 124 a higher basis weight of absorbent material than in the longitudinal direction 9 front and rear areas 126 . 127 , The basis weight of cellulosic fiber material is in the front and back regions 126 . 127 the absorbent body layer 122 in the exemplified case 162 g / m ² and in the central area 124 329 g / m ² . In addition, the absorbent layer includes 122 a total of about 7 g of superabsorbent polymer materials that are homogeneously uniform in the absorbent layer 122 are arranged distributed. The areas 126 . 127 and 124 are in the longitudinal direction 9 opposite the planar extension of the base layer 120 reset, as reflected 8th can be seen.

Finally, the absorption body comprises 7 a body-facing in exemplary and preferred illustrated hourglass-shaped Flüssigkeitsaufnahme- and -verteilerschicht 128 that are predominantly on the middle range 124 the absorbent body layer 122 extends. The fluid intake and distribution layer 128 projects beyond a belly section side longitudinal end 130 of the middle area 124 the absorbent body layer 122 , It comprises a basis weight of fibrous material, in the form of curled fiber of, for example, 149 g / m ^2, having a total mass corresponding to the exemplary extension of about 2.8 g.

The base layer 120 , the three areas 124 . 126 and 127 the absorbent body layer 122 and the body-facing fluid acquisition and distribution layer 128 have over their areal extension uniform basis weight of absorbent materials.

The basis weight is determined metrologically as described above by a specimen of 25 mm × 25 mm is considered by all the just described layers of the absorbent body 7 is punched out. The area to be punched 132 (25mm x 25mm) will always be relative to the longitudinal centerline 44 centered, as in 8th is indicated. When the basis weight in the longitudinal direction 9 is determined further forward or further back, the test specimen in a corresponding manner with respect to the longitudinal center axis 44 centered.

It can be seen that the weight per unit area of absorbent material thus starts from the transverse center axis 30 along the longitudinal central axis 44 in the direction of a belly section end 134 and toward a spine end 136 of the absorption body 7 gradually decreases. In this way, between the steps plateaus 138 educated. In the area of these plateaus 138 is the basis weight of absorbent material of the underlying layers of the absorbent body 7 preferably but not necessarily constant.

In the illustrated preferred embodiment of the incontinence article is the basis weight of the absorbent body 7 starting from the transverse center axis 30 forward and backward in the area of overlap of the body-facing fluid intake and distribution layer 128 with the central area 124 the absorbent body layer 122 essentially constant.

One recognizes in 8th and 9 plateaus 140 . 141 that are in a gradation 142 . 143 longitudinal 9 connect to the front or rear. In the area of these plateaus 140 . 141 is the basis weight of the absorption body 7 relative to the basis weight in the region of the transverse center axis 30 significantly reduced.

It will now be based on the 8th . 10 and 11 describes the folding of the panty-shaped incontinence article for the stacked arrangement of a plurality of incontinence articles in a package for dispensing on the market: As already mentioned forms the transverse central axis 30 a first folding axis 150 around which the incontinence article is folded so that belly section 4 and back section 6 for the formation of side seam areas 14 can be permanently joined together, by conventional joining methods such as gluing, ultrasound, etc .. Furthermore, are approximately in the longitudinal direction 9 extended second fold lines 152 in 8th merely hinted at, since the folding is not in the in 8th shown expanded state, but after completion of the panty-shaped incontinence article in the in 10a only schematic sketched state. Starting from this in 10a Outlined condition will be on both sides in the transverse direction 16 laterally over the crotch section 8th protruding areas 154 of the belly section 4 and back section 6 in Direction to the longitudinal central axis 44 , Preferably on the outside of the belly section 4 , hit, so that in 10b approximately sketched configuration is obtained.

Finally, the show 8th and 10 a third in the transverse direction 16 extending folding axis 156 their position relative to the absorption body 7 out 8th evident. With further folding around this only further in the transverse direction 16 extended folding axis 156 will the in 10c obtained shown compact folded configuration of the panty incontinence article. It can be seen that the the hip opening 18 limiting waistband 17 longitudinal 9 not over the first folding axis 150 formed outer folded edge 158 of the incontinence article.

Finally clarifies 11 in which places the thickness of the total in the configuration of 10c folded incontinence article 2 is determined. As already mentioned, the whole of this folded incontinence article 2 over the entire transverse direction 16 with a punching knife at a distance of about 10 mm from the folding edges or folding axes 150 and 156 stamped out so that strip-shaped specimens 160 be formed. Based on these all layers of the incontinence article covered examinees 160 Then the thickness is determined as described above.
